RC_PROXY_CONTROLFILE

This view contains descriptions of control file backups that were taken using the proxy copy functionality. It corresponds to the V$PROXY_DATAFILE view.

In a proxy copy, the media manager takes over the operations of backing up and restoring data. Each row represents a backup of one control file.

Column

Data Type

Description

DB_KEY

NUMBER

The primary key for the target database. Use this column to join with almost any other catalog view.

DBINC_KEY

NUMBER

The primary key for the incarnation of the target database. Use this column to join with RC_DATABASE_INCARNATION.

DB_NAME

VARCHAR2(8)

The DB_NAME of the database incarnation to which this record belongs.

XCF_KEY

NUMBER

The proxy copy primary key in the recovery catalog. If you issue the LIST command while RMAN is connected to the recovery catalog, then this value appears in the KEY column of the output.

RECID

NUMBER

The proxy copy record identifier from V$PROXY_DATAFILE. RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file.

STAMP

NUMBER

The proxy copy stamp from V$PROXY_DATAFILE.RECID and STAMP form a concatenated primary key that uniquely identifies this record in the target database control file.

TAG

VARCHAR2(32)

The tag for the proxy copy.

RESETLOGS_CHANGE#

NUMBER

The RESETLOGS SCN of the database incarnation to which this data file belongs.

RESETLOGS_TIME

DATE

The RESETLOGS time stamp of the database incarnation to which this data file belongs.

CHECKPOINT_CHANGE#

NUMBER

Data file checkpoint SCN when this copy was made.

CHECKPOINT_TIME

DATE

Data file checkpoint time when this copy was made.

CREATION_TIME

DATE

The control file creation time.

BLOCK_SIZE

NUMBER

The block size for the copy in bytes.

BLOCKS

NUMBER

The number of blocks in the copy.

MIN_OFFR_RECID

NUMBER

Internal use only.

OLDEST_OFFLINE_RANGE

NUMBER

Internal use only.

DEVICE_TYPE

VARCHAR2(255)

The type of sequential media device.

HANDLE

VARCHAR2(1024)

The name or "handle" for the proxy copy. RMAN passes this value to the operating system-dependent layer that identifies the file.

COMMENTS

VARCHAR2(255)

Comments about the proxy copy.

MEDIA

VARCHAR2(80)

A comment that contains further information about the media manager that created this backup.

MEDIA_POOL

NUMBER

The number of the media pool in which the proxy copy is stored.

START_TIME

DATE

The time when proxy copy was initiated.

COMPLETION_TIME

DATE

The time when the proxy copy was completed.

ELAPSED_SECONDS

NUMBER

The duration of the proxy copy.

STATUS

VARCHAR2(1)

The status of the backup set: A (available), U (unavailable), X (expired), or D (deleted).

KEEP

VARCHAR2(3)

Indicates whether this proxy copy has a retention policy different from the value for CONFIGURE RETENTION POLICY. Possible values are YES and NO.

KEEP_OPTIONS

VARCHAR2(11)

The KEEP options specified for this control file backup. Possible values are NOLOGS, BACKUP_LOGS, LOGS, and NULL. NOLOGS indicates a consistent backup made when the database was mounted. BACKUP_LOGS indicates that the backup was made in open mode, so archived log backups must be applied to make it consistent. LOGS indicates a long-term backup made with the LOGS keyword, which is now deprecated. NULL indicates that this backup has no KEEP options and becomes obsolete based on the retention policy.

KEEP_UNTIL

DATE

If the KEEP UNTIL TIME clause of the BACKUP command was specified, then this column shows the date after which this control file backup becomes obsolete. If the column is NULL and KEEP OPTIONS is not NULL, the backup never becomes obsolete.

CONTROLFILE_TYPE

VARCHAR2(1)

The type of control file copy: B (normal copy) or S (standby copy).

RSR_KEY

NUMBER

Unique key for the row in RC_RMAN_STATUS that created this backup piece.

SITE_KEY

NUMBER

Primary key of the Data Guard database associated with this file. Each database in a Data Guard environment has a unique SITE_KEY value. You can use SITE_KEY in a join with the RC_SITE view to obtain the DB_UNIQUE_NAME of the database.
